The next time you’re in California, you might not want to bring your cell phone with you. The California Supreme Court ruled Monday that police can search the cell phone of a person who’s been arrested — including text messages — without obtaining a warrant, and use that data as evidence.

The ruling opens up disturbing possibilities, such as broad, warrantless searches of e-mails, documents and contacts on smart phones, tablet computers, and perhaps even laptop computers, according to legal expert Mark Rasch.

The ruling handed down by California’s top court involves the 2007 arrest of Gregory Diaz, who purchased drugs from a police informant. Investigators later looked through Diaz’s phone and found text messages that implicated him in a drug deal. Diaz appealed his conviction, saying the evidence was gathered in violation of the Fourth Amendment, which prohibits unreasonable searches and seizures. The court disagreed, comparing Diaz cell phone to personal effects like clothing, which can be searched by arresting officers.
